Floating Cover
Engineering Calculators
Three free, sign-up-free engineering tools for floating cover projects — surface area with 3D preview, evaporation loss with live weather data, and heat loss / ROI using the ASHRAE pond model. Pick a calculator below.
Surface Area & Coverage Calculator
Calculate pond and tank surface area for rectangular and round shapes — with a live 3D cover preview.
- Frustum geometry handles sloped earthen ponds
- Multi-pond totals across an entire facility
- Imperial + metric, instant unit toggle
- WebGL 3D preview with AWTT product variants
Evaporation Loss Calculator
Quantify daily and annual pond evaporation using live weather data and the aerodynamic mass-transfer method.
- Real-time temperature, humidity, wind by site
- Aerodynamic mass-transfer (Magnus) physics
- Compare savings across 7 AWTT cover products
- Monthly chart + reservoir-type presets
Heat Loss & ROI Calculator
Engineering-grade heat loss and lifecycle ROI for heated industrial ponds. Five-component ASHRAE model.
- ASHRAE 5-component pond heat-loss model
- Brady-Graves-Geyer equilibrium temperature
- No Cover / Solid Cover / AWTT side-by-side
- Payback + 20-year lifecycle TCO
How AWTT engineers use these tools
The three calculators are designed to be used together. For a typical project quote we recommend the following order:
- 1Start with Surface Area — measure the pond once, get total ft² (or m²), and decide which AWTT product variant fits the geometry.
- 2Run Evaporation — feed the area into the evaporation calculator and quantify the annual water saved per cover product against your local weather.
- 3If your pond is heated, run Heat Loss & ROI — the calculator combines heating, chemical, pumping, and makeup-water savings into a single payback period and 20-year TCO comparison.
